Multifunction Digital ESC and Servo Tester with Speed Controller and Power Meter for RC Drones and Planes Overview A compact, multipurpose tester designed for hobbyists, model builders, and technicians who work with RC drones, planes, and other model electronics. This digital tool combines ESC testing, servo testing, speed control, and basic power measurement into a single, easytouse unit with replaceable accessory leads and adapters. Key benefits Faster diagnostics and setup: Quickly verify ESC and servo operation before installation to avoid infield failures and reduce troubleshooting time. Versatile compatibility: Works with standard hobby servos, brushless ESCs, and common RC battery and motor connections through included replaceable adapters. Simplifies tuning and comparison: Use consistent test signals to compare ESC behavior, calibrate throttle ranges, and check servo center and travel. Portable and practical: Compact form makes it easy to carry to the workshop or field for preflight checks and repairs. Main functions and practical attributes Multifunction capability: Acts as a digital ESC tester, servo tester, speed controller simulator, continuity and consistency checker, and a basic power meter for monitoring current draw patterns. Compatibility: Designed for RC model applications including drones and fixed wing planes, compatible with standard hobby servo connectors and common ESC inputs through interchangeable leads. Size and build: Small and lightweight for bench work and field use, housed in a durable plastic enclosure with reinforced connector points for repeated use. Performance: Provides stable digital output signals for precise throttle and servo control, enabling repeatable testing and reliable comparison across components. Replaceable accessories: Includes multiple connector leads and adapters that can be swapped to match different ESC, servo, and battery interfaces, extending the tester lifespan and flexibility. Use scenarios Preflight verification: Confirm servos move correctly and ESC throttle responds before mounting components on a build or after repairs. Bench testing ESCs and motors: Compare throttle response and current draw of different ESCs or propeller setups to identify inconsistent units or optimize performance. Installation and calibration: Set servo centers and travel, calibrate ESC throttle endpoints, and verify power draw during propeller or gear changes.
